the color is red
Red is the high side.. The low side is blue..
On a manifold gauge set, there are two gauges. The gauge encased in red measures pressure on the high pressure (discharge) side. That's the "high side gauge". The other will be incased in blue, and measures vacuum pressure on the low side.
Blue
The low side gauge more than likely says retard because you hooked the low side up on the high side port
On a 1996 Ford Crown Victoria : The H / L ( High / Low ) gauge : On the drivers side of the speedometer is the battery voltage gauge On the passenger side of the speedometer is the engine oil pressure gauge

its orange and it is located on the right side of the gauge cluster
When checking a/c system operations. There are two gauges that measure high side and low side pressures.
Using a gauge and the proper type of freon, connect to the low side ac gauge. With the ac on high and the engine running fill the system to the full mark on the gauge.
The port next to the radiator is the low-side port
Connect freon and a gauge to the low side ac port. Fill the system to full on the gauge, with the engine running, and the ac on high.
